Celestron Omni XLT 102mm refractor

Hey guys I’m a total newb. How wanted to do astrophotography and just looking through a telescope, did a lot of research (not enough) and with my limited funding bought a celestron dx5 explorer SCT. Tube is great everything else sucks. Can’t even track mars enough to take a picture. Lots of plastic in this design and it is an alt-az. I almost bought a Celestron (coincidence of the brand being the same I like skywatcher more) Omni XLT 102 refractor with a German eq mount. Would that have been better for casual use and also astrophotography? Maybe I can try and sell my setup and get that, it’s $700. Please let me know what you think.
